aziel-runtime

Step 2 — Describe the slug you picked

fraggate_describe

Read-onlyIdempotent

Inspect one FragGate card by name or slug to check live, stub, or local_only status, public ops, and engine digest. Use when you already have a software identifier.

Instructions

Inspect one FragGate card for the slug you picked from Softwares (live vs stub vs local_only, public ops, engine_digest). Not execute and not a digest-only proof. Use this when you already have a name or slug from Softwares, fraggate_list, or GET /v1/software. Do not use it for discovering the full registry, proving a digest, pulling a hub product card, or executing an op; use fraggate_list, fraggate_verify, runtime_pull, or fraggate_call instead. Missing both name and slug, or an unknown name, refuses FG-HALLUC-TOOL. Wipe/unlock on embryolock stay FG-STUB. AZChat is LIVE+bound (mesh default off; not AZMail). Pass name or slug — one is enough. Combined name/op forms such as foldlock/fold-preview are accepted. Returns one registry card (ops, stub_ops, digest, status, aliases).

Input Schema

TableJSON Schema

Name	Required	Description	Default
`name`	No	Optional registry display name (for example FoldLock, EmbryoLock, AZHub). Use name or slug — one is enough. Combined name/op forms such as foldlock/fold-preview are accepted by the door parser. Unknown names refuse FG-HALLUC-TOOL.
`slug`	No	Optional catalog slug (lowercase a-z0-9-, for example foldlock, embryolock, azhub). Alternative to name. Prefer the slug returned by fraggate_list or GET /v1/software.

Output Schema

TableJSON Schema

Name	Required	Description
`code`	No	FragGate or fabric code when present: FG-OK, FG-HALLUC-TOOL, FG-STUB, FG-LOCAL-ONLY, FG-UNKNOWN-OP, FG-GATE-REFUSE, FG-LAMB-REFUSE, or a module refuse such as MESH-* / AKM-*.
`door`	No	Door name. The public door is fraggate.
`ran_in`	No	Execution locale (for example aziel-runtime) when present.

TDQS

A4.3/5.0

Behavior4/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations already declare readOnly, idempotent, non-destructive, closed-world, so the safety profile is covered. The description adds real behavioral context beyond them: failure mode (missing name and slug, or unknown name, refuses FG-HALLUC-TOOL), stub/live status semantics, and a note that it is 'not execute and not a digest-only proof'. It stops short of describing response shape, but an output schema exists so that is not required.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Dense and front-loaded: the purpose and the not-this routing come first, then edge cases, then the return. It is longer than most descriptions and repeats the sibling list, but each clause carries operational information (error codes, live/stub, accepted forms).

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given a low-complexity 2-param read tool with full annotations and an output schema, the description covers purpose, routing, failure modes, and status semantics. What remains (exact card fields) is covered by the output schema, so the definition is complete enough to call correctly.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100% and the schema already documents that one of name/slug suffices, the combined name/op form, and the FG-HALLUC-TOOL refusal. The description's param remarks largely restate that ('Pass name or slug — one is enough'), so it adds little beyond the structured fields; baseline 3 is appropriate.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific verb (inspect/describe) and resource (one FragGate registry card) plus the scope ('for the slug you picked'), and explicitly distinguishes itself from fraggate_list, fraggate_verify, runtime_pull, and fraggate_call. An agent can pick this tool over its siblings without opening any schema.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines5/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Gives an explicit when-to-use trigger ('when you already have a name or slug from Softwares, fraggate_list, or GET /v1/software') and an explicit when-not list mapped to named alternatives. Nothing is left to inference.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
